Color effects from transparent 3D printed nanostructures

(Institute of Science and Technology Austria) Structural coloration means that the microstructure of an object causes various colors to appear. For industry, this is an attractive alternative to coloring with pigments. But so far, scientists had primarily experimented with nanostructures observed in nature, or with simple, regular designs. Computer scientists from IST Austria and KAUST now take a different, innovative approach: their tool automatically creates 3D print templates for nanostructur...
